Hsp90 is a promising therapeutic target for the treatment of cancer. Novobiocin is the first Hsp90 C-terminal inhibitor ever identified and recent structure–activity relationship studies on the noviose sugar identified several commercially available amines as suitable surrogates. In an effort to further understand this region of the molecule, analogues containing various N′-amino substituents were
Hsp90 是治疗癌症的有希望的治疗靶点。Novobiocin 是第一个被发现的 Hsp90 C 末端抑制剂,最近对 noviose 糖的结构-活性关系研究确定了几种市售胺作为合适的替代物。为了进一步了解分子的这一区域,制备了含有各种 N'-氨基取代基的类似物,并针对两种乳腺癌细胞系进行了评估,以确定它们的功效。从这些研究中,化合物37j表现出最有效的抗增殖活性,并在中等纳米摩尔浓度下诱导 Hsp90 依赖性客户蛋白降解。
